“…Similarly, the variant mode of operations of the BS (e.g., during low traffic or peak traffic mode) also has an impact on the energy consumption pattern of the BS [91,92]. For the case of mobile and wireless telecommunication networks, the end users are connected to the BSs through a wireless channel, where each of the BSs is connected to other networks via a wireless point-to-point link or wired-based connection [92,93]. At present, several wireless access technologies have existed, and the latest one is LTE (Long-Term Evolution), similarly known as 4G technology, and 5G technology will be deployed soon [93].…”

“…to the power consumption and vice versa for the case of the power consumption metric [94]. To improve the energy efficiency of BSs, strategies such as reduction of the BS energy consumption through sleep or idle mode [3,9,92,93,95]; device-to-device (D2D) communication [96]; utilization of high efficient technologies (i.e., improved power amplifiers, high-efficient air conditioning systems, cognitive radio technology, as well as fixed and cooperative relays) [3,15,16,92,95,97]; critical energy management [98,99]; proper sizing and optimization of the power supply system [10,13]; site sharing and heterogeneous cellular networks [3,92,99,100]; as well as cell shaping and an increased number of carrier frequencies [94,95] can be deployed to achieve the energy efficiency of BSs at various levels.…”

Abstract:The telecommunication sector plays a significant role in shaping the global economy and the way people share information and knowledge. At present, the telecommunication sector is liable for its energy consumption and the amount of emissions it emits in the environment. In the context of off-grid telecommunication applications, offgrid base stations (BSs) are commonly used due to their ability to provide radio coverage over a wide geographic area. However, in the past, the off-grid BSs usually relied on emission-intensive power supply solutions such as diesel generators. In this review paper, various types of solutions (including, in particular, the sustainable solutions) for powering BSs are discussed. The key aspects in designing an ideal power supply solution are reviewed, and these mainly include the pre-feasibility study and the thermal management of BSs, which comprise heating and cooling of the BS shelter/cabinets and BS electronic equipment and power supply components. The sizing and optimization approaches used to design the BSs' power supply systems as well as the operational and control strategies adopted to manage the power supply systems are also reviewed in this paper.

We target the problem of managing the Base\ud Stations (BSs) lifetime and their energy efficiency when a sleep\ud mode (SM) is adopted. We first show that the BS lifetime is\ud affected by two opposite effects: the duration of SM, which tends\ud to increase the lifetime, and the SM frequency, which on the\ud contrary decreases the lifetime. After optimally formulating the\ud problem for a cellular network, we propose a new heuristic,\ud called LIFE, to practically solve it. Our solution integrates the BS\ud lifetime when SM decisions are considered. Results, obtained over\ud an UMTS scenario and a LTE one, prove that LIFE outperforms\ud two previous energy-efficient algorithms in terms of lifetime\ud performance, since all the previous solutions tend to drastically\ud reduce the BS lifetime. Moreover, we show that LIFE is able to\ud save up to 40% of power during night in the long-term

“…With the fast development of wireless technologies [2,3] and wide deployment of 3G/4G/LTE base stations and WiFi hotspots [4,5], the mobile devices can be connected to the Internet at anytime and at anywhere [6], where the communication among peers becomes more convenient. On the other hand, the storage capacity of mobile devices is increasingly large [7].…”

The mobile devices have become the norm, rather than an exception for people's daily life, and these devices possess strong ability (e.g., increasingly large storage) to serve as content sources in future information-centric networks, e.g., named data networking (NDN). The efficient discovery of contents provided by mobile devices is a challenging task. Most of existing studies adopted ID-Locator split architecture to handle the problems raised by source mobility in NDN, e.g., the content source is suddenly disconnected from the network when providing on-going services. However, these solutions require very high control overhead to maintain upto-date location information of sources in an ID-Locator mapping system. Software defined networking (SDN) is a promising tool to make cross-layer decisions based on its logically centralized controller, and thus can facilitate the implementation of forwarding strategies in NDN according to application requirements. To this end, this paper proposes a new packet forwarding algorithm under SDN paradigm that is able to update the forwarding information base (FIB) of NDN node considering both the mobility pattern of mobile sources and network states. In particular, the algorithm leverages the SDN controller to perform the tradeoff between global FIB updates on all NDN nodes and local FIB updates on NDN nodes that are previously connected by mobile sources to lower the control overhead. A discrete-event simulator based on NS3 simulation framework is developed to validate the effectiveness and feasibility of the proposed algorithm. In addition, the performance of the algorithm is compared with that of existing solutions based on ID-Locator split architecture. The results show that the proposed packet forwarding algorithm has a lower request-to-response latency and higher successful content request ratio with reduced control overhead under different working conditions.
